Kwa and the Ape People by Perley Poore Sheehan

KWA sent his second rock humming at Anansi's head. It checked the rush of the spider chief. There was satisfaction in that. Something of the haunt that was forming in Kwa's own mind--the feeling that he was fighting against something supernatural--left him. In an instant it was as if something supernatural had been infused into his own heart and brain.

It may have been a thought prompted by something else that happened just then. For a moment Anansi was beset by another enemy. There was a rush of many black wings and a flock of ravens had spun around Anansi's head. At the same time they were shrilling out in their tribal speech--cries so filled with human meaning that almost anyone could have understood them. They were telling Kwa to run--to save himself while they created this diversion.
